Testování mechanických vlastností lepených spojů Al slitin s pomocí metody DIC

Abstract

This diploma thesis deals with increasing the mechanical properties of the glued joint in aluminium alloys by pre-treatment the surface of the glued joint with laser technology and a description of the processes taking place in the tensile test. In the first part, this work deals with theories about the formation of adhesive forces in the glued joint and surface pre-treatment of glued surfaces of aluminium alloys. The second part deals with tests of mechanical properties of glued joints and methods of measuring displacement with emphasis on the method of digital image correlation (DIC). The third part with a rounded design and implementation of individual experiments, including tensile tests with the support of DIC methods. The last part is an evaluation of the results and benefits of the whole experiment.
